INKING MECHANISM FOR PRINTlNG -MACHINES.

SPECIFICATION forming part of Letters Patent No. 298,147, dated May 6. 1884.

\ Application filed August 23, 1883. (No model.)

Be it known that I, Geode ASHLEY WIL- soN, a subject of the Queen 0 Great Britain, residing at Liverpool, in the county of Lancaster, England, have invented a new and useful Improvement in Inking Mechanism for. Printing-Machines, of which the following is a specification.

My invention relates to apparatus for carry ing ink from the inking-trough roller or ink ductor-cylinder to the ink-distrilnlting drum or table of printing-machines.

The main objects are to provide mechanism or apparatus in which the motions of the carrying-roller which takes ink from the troughroller or ductor-cylinder and gives it to the drum or table may be adjusted and regulated with greater precision than heretofore, so that the requisite quantity of ink, and neither more nor less, may be deposited on the drum or table, and to allow of the whole or parts of the apparatus being easily disengagtd or thrown out of gear, so that they may be separately adjusted to their work; lattain these objects by the mechanism illustrated. inqthe accompanying sheets of drawings, where- Figures 1 and 2 are views! of Ithe opposite ends of the machine embodying iny invention, the distributing-(liram 26 having been omitted in Fig. 2. Fig. 3 is a side elevation, parts and the distributingd rum, carrying-roller, and bell-crank lever by which the latter is actuated having been omitted for sake of clearness. Fig. 4 is a horizontal section through the driving-wheel 6 and its clutch mechanism. Fig. 5 isasimilarsection through the eccentric 1 4. and its connections. 6 is an elevation of collar 7.

Like figures refer to like parts wherever they occur.

1 is part of the framework of the printingmachine; 2, ink-trough, of usual construction, secured to the frame in any suitable manner, such as by bolts and nuts; ,3, dilator-cylinder carried by shalt 4 andworking imbearings 5; 6, driving-wheel fitted to work fnecly on their shaft 4 and held in positionby the collars 7 8, secured to the said shaft by set-screws 9.

To all whom it may ed n f $1,

The collar 7 has inclined curved grooves 10 cut therein, into which takesa pin, 1]., fitting into a recess in the boss of the wheel 6. 12 is a helical spring fitting in the before-mentioned recesses behind the pin 11, so as to keep it pressed against the face of the collar 7. More than one pin may be used, and the number of slots 10 may be varied. This construction enables me to change the relation of the cylinder 3 to the driving mechanism and to adjust it with relation to the carrying-roll 25 Without disturbing the driving mechanism.

In practice I find two slots and one pin answer well when the wheel and collars are castiron and the pin steel. The above construction allowsof the inking apparatus being turned forward for adjustment or otherwise without moving the driving-wheel 6 or the rest of the machinery, as the pin 11 travels along the slots 10, and is gradually pushed back by the inclined surface. X Vhen forward mot-ion is given to the driving-wheel, the pin moves into the deep end of one of the slots and carries round the collar '7, and with it the inking apparatus. Collars 13, fixed to the shaft 4, retain between them the loose eccentric Li. Theloose eccentric ll is formed or provided with a projecting piece, 15, adapted to fit against aprojecting piece, 16, on the boss of the hand-wheel 1.7. The handovhecl 17 is free to slide to and fro on the shaft awithin the limits allowed by the fixed collars i3 and 18, so that the projections 15 and 16 may be caused to engage and disengage. 1.) is a key fitted securely to the shaft at and freely within a slot in boss of the hand-wheel l7 2-0, eccentric-strap, from which extends an arm, 27, that is connected with bell-cran k lever 23, and imparts motion thereto; 21, pin; 22, slot in bell-crank lever 23, by which means the connection between the cocentric and bell-crank lever may be adjusted to vary the throw of the bell-crank lever and the travel of carrying-roller 25; 24, fulcrum pin or bearing for lever 23; 25, carrying-roller in bearings on the upper end of the lever 23,- 26, distributing drum or table. hen the hand-wheel is in the position shown in the drawings, motion may be given to'the (luGtOrcylinder 3 without imparting motion to the eccentric 11- and carrying-roller 25. NVhen the haml-wheel is moved close against the eccentric, so that the projecting pieces 15 and 16 are in contact, any motion imparted to the duetor-cylinder 3 will be imparted through the boss of the hand-wheel 17 to the eccentric 14, and thence to the carrying-roller 25. The said hand-wheel serves as means for giving motion to the inking mechanismindependently of the driving-wheel 6, so that the inking mechanism may be set in motion, the rest of the machine being at rest, for the purpose of 10 judging whether any and what adjustment of 1. In inking apparatus for rotary printing I mechanism, the combination, with the dnctorf shaft, of an eccentric loose upon the shalt and 1 provided with a projecting pin or (clutch-piece, a sliding hand-wheel splined to the shalt and provided with a pin or clutch-piece, a carrying-roller, and interposed mechanism, substantially as described, for actuating the earrying-roller from the eccentric of the ductorshalt, substantially as and for the purposes specified.

2. In inking apparatus for rotary printingmachines, the combination, with the doctorshal't, o'fan eccentric and devices, substantially as described, for causing the same to move with the shalt, an eccentric-strap having an arm provided with a pin, 2]., an elbow-lever having its lulcrun'i at the angle and one arm slotted for the adjustment of the pin 21, and a carrying-roll journaled on the vertical arm of the elbmv-lever, substantially as and for the purposes specified.

3. The combination of the shaft 4, drivingwheel 6, and disel'lgaging mechanism with the hand-wheel 17 and clutch mechanism, and the eccentric 14: and carryingroller and conneclions, substantially as set forth.
